Wave Types/Vibrations
What is Transverse Wave?
A wave in which the wave motion is perpendicular to the particle motion
What is Wavelength?
The distance from any point on a wave to and identical point on the next wave.
What is Reflection?
The bouncin back of a wave when it meets a surface or boundary.
What is Pitch?
The quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.
Light Waves are also called electromagnetic waves because?
They consist of changing electric and magnetic fields
What is a Longitudinal Wave?
A wave in which that wave motion is parallel to the particle direction
What is Amplitude?
The maximum distance that the particles of a wave’s medium vibrate from their rest position
What is Diffraction?
A change in the direction of a wave when the wave find an obstacle or an edge, such as an opening.
Sound waves are longitudinal waves caused by?
Vibrations and carry energy through a medium.
The Two Most Common Models describe Light as?
a wave or a stream of particles
What is a Medium?
A medium is a physical environment in which phenomena occur
What is a Period?
The time for a particle on a medium to make one complete vibrational cycle.
What is Refraction?
The bending of waves when they pass from one medium into another.
What does the Speed of Sound Depend on?
It depends on a medium.
The energy of light is proportional to?
Frequency
What are Circular Waves that Spread out called?
Fronts
What is Frequency?
The number of wavelengths that pass a point in a given time interval.
What is Interference?
The combination of two or more waves that result in a single wave.
Loudness is determined by?
Intensity
Red Photons have?
Low energy; low frequency (4.5x10^14 Hz)
How do most Waves Travel?
Through a Medium
The Speed of a Wave is equal to what?
To the wavelength divided by period, or to frequency multiplied by wavelength.
What is the Difference Between Constructive and Destructive Interference?
Constructive interference increase amplitude while Destructive interference decreases amplitude.
The Human Ear can Hear how many Hertz?
20-20,000 Hertz
Ultraviolet Photons have?
High energy: have about twice the frequency(9.0x10^14 Hz)
